Coolant: Testing and Inspection

INSPECTION

HINT:  Check the coolant level when the engine is cold.

1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR

The engine coolant level should be between the "LOW" and "FULL" lines at normal temperature (20°C (68°F)).
If low, check for leaks and add "TOYOTA Long Life Coolant" or equivalent up to the "FULL" line.

DO NOT FURTHER DILUTE PRE-MIXED MANUFACTURER APPROVED ETHYLENE GLYCOL BASED COOLANT IF USED.
MIX ACCORDING TO THE MANUFACTURER'S DIRECTIONS.

2. CHECK ENGINE COOLANT QUALITY

a. Remove the radiator cap.

CAUTION:  To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.

b. There should not be any excessive deposits of rust or scale around the radiator cap or radiator filler hole, and the coolant should be free from

oil.
If excessively dirty, clean the coolant passages and replace the coolant.

c. Reinstall the radiator cap.
